Patented Aug. 4, 1908.

Application led October 15, 1906. Serial No. 338,953.

To all 11:72am it may concern:

Be it known that I, EMIL DEisriziz, a citizen of the United States of America and resident of Fort ylivziyiie, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Feeding Devices for Ore-Concentrators, of which the following is a specification.

This invention relates to improvements in feed devices for ore concentrators, and the object thereof is to provide compensating meansfor irregularity of feed and to relieve the table of surplus water.

The above object is accomplished by the construction illustrated in the accompanying drawings in which Figure 1 is a plan view of the invention shown in connection with a concentrating table; Fig. 2 is an enlarged transverse section of the same on the line r-m of Fig. 1 and Fig 3 is an enlarired longitudinal section on the line y-y of lig. 1.

Similar numerals of reference indicate correspondiinT parts throughout the several vcr Cit

views, ant referring now to the same: `1 is' a concentrating table, 2 is the head-board along the feed side of the table, and 3 is the projecting breast-board at the rear end thereof. v

The invention consists of the feed box 4 which is divided partway of its length bjr a partition thus affording a feed chamber 6 for the reception of pulp, and a set tliug chamber T into which passes surplus pulp from the former chamber.

-i waste launder S leads from the rear end of the settling chamber, and a wedge shaped block forms a dam 9 at its juncture with the launder. Another wedge shaped block forms a shoal 10 at the forward end of the box and prevents the pulp from s ilashing.

In the feed chamber G is a projecting niet-al plate 11 adjacent the side nearest the headboard 2, and feed openings 1'2 are made therein which `register with larger corre-Q the partition 5 in a slanting direction towar the row of feed openings and serves to divert the pulp in the feed chamber toward said openings '12, and allow the settled ymineral to pass to the'opening 15.

ln the operation of this invention the table,

together with the box, is reciprocated in the t direction indicated by the arrow, and pulp is fed into the feed chamber at the rear endthcreof. The pulp is discharged from the box through the feed openings, that portion lying above the plate 11 passes out through the openings 12 and the 'settled matter passes vention is that, in case of a sudden rush of pulp, the overlying port-ion thereof overflows the riflle 17 and enters the settling cnaniber 7 wherein the mineral ravitatcs to the bottoni and because of the ldifferential action of the table is moved to the opening 15 and is discharged. Should the pulp rise in the settling chamber above the level of the dani 9, the surplus water, after being relieved of its contained mineral, overflows into the waste laundcr and is discharged therebt without passing onto the table. tieial since the sudden rushes of water upon the table disturbs the strata of ere matter thereon which is detrimental to concentration.

Having described my inventieEl what I claim as new and desiie to secure by Let-ters Patent isz- 1. In apparatus ofthe 'class described, a reciprocating table; a feed box in connection with the table, having a feed chai-aber and This is highly bcne settling chamber which have communication at t-hc forward end of the former, the feed chamber having discharge openings which extend through the bottom of the box, and the set tlingr chamber having a shoai at its forward end and a dam at its rear end. `and havchamber at. its rear end adapted to receive the overflow therefrom which passes over the 2f v v 895,075

adjacent dam, and being,r adapted also to convey thesame away from the table.

2. In apparatus of the class described, a reciprocating table; a feed bo.\ in connection its length by a partition, one part for a v'eed chamber and the other fora settling,r chamber, the feed chamber having a series of feed openings in its bottom, and the settling chamber having a feed opening at its forward end and a dam at its rear end; and a waste launder communicating with the settling chamber at its rear `end adapted to receive the overflow which passes therefrom over the dam, and convey the waste away from the tbl. l

3. In apparatus of the class described, a reciprocating table; a feed box secured to the table and having a feed chamber and settling chamber, the former communicating with the latter; an upwardly projecting plate in the feed chamber, havmg feed openings therein which extend through the bottom of the box, the settling chamber havin@ a discharge openinv in its bottom near its foro with the table, which is divided part-way of lllying mineral in the feed charnbertoward said openings; and awaste launder comy munzcatlng with the setthnu' chamber at a.

, point above the level of' its bottom, and beilwA 30 g adapted to convey overtlow water from box away from the table.

4. In apparatus of the class described, a reciprocatinr table; a feed box secured t0 the table, having av feed chamber and settling 3.5 chamber which communicate with one. another, and having also discharge openings leading from the feed chamber and another discharge 'opening near the forward end of the settling chamber; an upwardly project- Le ing plate in the feed chamber, having openings therein which communicate with thel openings which lead from the sett-ling chamber and an overflow outlet adapted to disaway from the table.

In testimony whereof I afilx my' signature, in presence of two Witnesses.
